A Study on the Design of a New Three-Dimensional Seismic Isolation Bearing Based on an Improved Genetic Algorithm for Bridge Engineering

Applied Sciences
(1) Background: In most cases, passive isolation control methods are commonly used for the seismic isolation design in bridge engineering. However, passive seismic isolation devices, due to their non-adjustable performance parameters, struggle to achieve

SEISMIC DESIGN FOR INFRASTRUCTURES

Jurnal Ilmiah Teknik Sipil
Seismic design for infrastructures such as building and non-building is designed based on design ground shaking shall be characterized by the design spectrum. This study aims to evaluate seismic design for infrastructures following SNI 1726-2019. Several site investigations are taken by conducting boring to a depth of 30 m to count the soil site ...
